GAS-BURNER.

Specification of Letters Patent.

Patented Apr. a, rare.

Application filed March 24, 1917. Serial 1\l'o. 157,072.

To all whom it may concern:

Be it known that I, SEBASTIANO M R- TOCCIO, a citizen of the UnitedStates, residing at the city of New York, borough of Manhattan, in thecounty and State of New York, have invented certain new and usefulImprovements in Gas-Burners, of which the following is a full, clear,and exact specification.

This invention relates to improvements in stoves and ranges, and thelike, adapted to be operated by a fluid fuel, and the same has for itsobject more particularly to pro vide a burner for the fuel which will beeconomical in its operation and simple in its construction.

Further, the invention has for its object to provide a burner comprisinga plurality of mixing chambers provided with means for admitting a fluidfuel to any of the mixing chambers independently of the others thereof.

Further, the invention has for its object to provide a plurality ofunits or sections comprising a mixing chamber and pipes communicatingtherewith together with means for admitting a fluid fuel to the mixingchamber whereby burners of di'fierent sizes may be formed by theassembling of two or more of the units or sections.

Further, the invention has for its object to provide a stove or range ofthis type with heat-retaining members which are so supported within thefire-pot that their weight is not borne by the burner.

Further, the invention has for its object to provide a stove or range ofthis type with heat-retaining members which are so supported within thefire-pot that they-are all positioned above the outlet openings of thepipes of the burner.

@ther objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends, my inventionconsists in the novel details of construction, and in the combination,connection and arrangement of parts hereinafter more fully described andthen pointed out in the claims.

In the accompanying drawing showing two illustrative embodiments of theinven tion Figure 1 is a front view of a range with the improved burnerapplied thereto, parts being broken away;

Fig. 2 is a sectional viewtaken on the line 2-2 of Fig. 1, part or" theheat-retain ing members being removed;

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1, and

Fig. 4 is a perspective view of one of the sections or units of amodified form of burner.

While the improved burner may be used in connection with any suitabletype of stove or range, it is shown, for purposes of illustration, asapplied to a French range.

Referring to the drawing 10 indicates a range having a fire-pot 11located between ovens 12, 12, as is usual in French ranges. Positionedwithin the firepot 11 and supported in any suitable manner, as forexample, by brackets 13 is the burner.

As shown in Figs. 1, 2 and 3 the burner comprises a hollow casting 1 1provided with a plurality of longitudinally extending partitions 15forming a plurality of mixing chambers 16 arranged side by side. Asshown the casting 1 1 has five mixing chambers 16 formed therein but itis, of course, understood that this number may be varied withoutdeparting from the spirit of the invention.

The upper wall of each of the mixing chambers 16 is provided with aplurality of outlet openings arranged in a row and extendinglongitudinally thereof, and the lower wall of each mixing chamber 16 isprovided with an inlet opening 18.

Communicating with the outlet openings of the mixing chambers 16 andextending upwardly therefrom are plurality of rows of pipes or nozzles19, 20 and 21. The pipes 19, communicating with the outlet openings ofthe central mixing chamber, are straight and their upper ends terminatebelow the top plate of the range a suiiicient distance to form a spacebetween the top plate and the ends of the pipes for a purposehereinafter described. The pipes 20, communicating with the intermediatemixing chambers 16, are of the same height as the pipes 19 and areprovided, intermediate their ends, with laterally and upwardly extendingbranches 20' the upper ends of which are in the plane of the upper endsof the pipes 19 and 20, and are preferably spaced from the upper ends ofthe pipes 20 a distance equal to the distance between the upper ends ofthe pipes 19 and the upper ends of the pipes 20. The pipes 21,communicating with the outer mixing chambers 16, are of w ll less heightthan the pipes 19 and 20 and their upper portions are inclined outwardlyand terminate adjacent the walls of the ovens 12, 12 in order to directthe flame thereagainst.

22 indicates a gas pipe leading from a suitable source of gas supply andprovided with branch pipes 23 communicating with the air supply pipes24: having their inner ends connected to the inlet openings 18 of themixing chambers 16. The branch pipes 23 are provided with valves 24L tocontrol the flow of gas therethrough and the pipes 24 are provided withregulating valves of any suitable type to regulate the amount of airpassing therethrough.

Supported above the upper ends of the pipes 19 and 20 in any suitablemanner, as by brackets 25, is a grid or grate 26 having the openingsthereof registering with the upper ends of the pipes 19 and 20 and thebranches 20. The space between the grate 26 and the top plate of therange is filled with a plurality of heat-retaining members 27 of anydesired form, made of lire-brick, fire-clay, lava, or any other suitablerefractory material. The heatretaining members 27 conserve and store theheat from the flame, thereby effecting a saving in the amount of gasconsumed during the use of the range, and as all of the members 27 arepositioned above the burner they will all be heated to substantially thesame extent.

Referring to Fig. 4: illustrating a modiflcation of the invention, 28indicates one of a plurality of units or sections of which the burner iscomposed. Each unit or section comprises a mixing chamber 29 providedwith a plurality of pipes 30 extending upwardly from its upper surfaceand communicating with the interior thereof. Fluid fuel is supplied tothe mixing chamber 29 of each section or unit 28 through an inletopening 31 in its lower wall in the manner above described. While thepipes 30 of the section shown in Fig. 4 are similar to the pipes 19associated with the central mixing chamber 16 of the burner shown inFigs. 1, 2 and 3 it will, of course, be understood that other units orsections may be provided having pipes similar in construction to thepipes 20, and 21 associated with the intermediate and outermixingchambers of the burner shown in said figures. The sections orunits 28 of the burner are placed side by side and the number of unitsor sections employed in any instance to form a burner will, of course,depend upon the width of the fire-pot of the stove or range in which theburner is to be installed.

In operation if the maximum amount of -heat is required for cooking orother purposes, all of the pipes 19, 20 and 21 of the burner areutilized. If the ovens 12, 12 are not to be used, but the maximum amountof heat is required at the top plate of the range the pipes 19 and 20are utilized, whereas if only a moderate heating of the top plate isdesired the fuel supply to one or more of the rows of pipes 19 and 20may be cut off by closing the appropriate valve orv valves 2 1 and theremaining row or rows utilized thereby effecting a saving in theconsumption of gas. In either instance a further saving of gas may beeffected by cutting off the supply to one orrnore of the rows of pipes19 and 20 after the heat-retaining members 27 have become thoroughlyheated as they retain the heat that they have absorbed for aconsiderable period of time.

Should it be desired to use only one or both of the ovens, one or bothof the rows of pipes 21 are utilized thereby insuring that none of thegas being consumed by the burner will be wasted.

Having thus described my said invention what I claim and desire tosecure by Letters Patent is 1. A burner comprising a. plurality ofcontiguous mixing chambers having pipes communicating therewith andextending upwardly therefrom, the pipes communicating with certain ofsaid mixing chambers being of less height than the pipes communicatingwith the other of said mixing chambers and having their upper portionsextending outwardly, each of said mixing chambers beine provided withmeans for admitting fluid fuel thereto, substantially as specified.
